Application October 20, 1942,' Serial .No. 462,768 ciaims. (c1. @1 -st) This invention relates to a joggle wedge which may be employed wherever itis desired to hold an object against movement by a wedging action and is especially adapted for use on marine ways when constructing ships and the launching thereof.

The primary object of the invention is the provision ofa device of the above stated character, which may be easily and quickly installed and released from the holding position without mutilation or damage occurring thereto, and Vwhich Will require less man-power in the launching of ships if employed for this purpose and a device which may be used as many times as desired.

With these and other objects in view as will become more apparent as the description proceeds, the invention consists of certain novel features of construction, combination and arrangement of parts as will be hereinafter more fully described and claimed. I f

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawings, in which-y Figure 1 is a front elevation partly in section, illustrating a joggle wedge constructed in accordance with my invention and showing vthe same in a holding position.

Fig. 2 is a fragmentary side elevation, illustrating a exible bail for releasablysecuring one" of the side members of the wedge in holding position. f Fig. 3 is a sectional view taken on the line 3-3 of Fig. l. y Y

Fig. 4 isa perspective view illustrating-one ofv the members of a coupling.

Fig. 5 is a diagrammatical Viewv showing the present invention in use on a marine Way.

Referring in detail to the drawings, the numeral 5 indicates the substantially rectangular frame including side members 6 and 'I and end members 8 and 9. The side member 6 and end member 8 are of integral construction with said members arranged at right angles to each other. The end member 8 has formed in one face thereof a notch 9 to be engaged by the beveled end I0 of the side member 1. Pivoted on the side member 1 is a exible bail I I' which when brought into engagement with the end member 8 will sustain the beveled end l0 of the side member I in the notch 9. It will be noted that the notch 9' islocated a limited distance from the free end of the end member 8 so that the free end of the member 8 will act as a stop for limiting the sliding movement of the frame between objects A and B. The object A is xed while the object B 65 is movable longitudinally of the object A.' -The frame is-positioned as shown in Fig.v 1 between the objects A and B with the free end of the end member 8 resting on the object A.` With the frame between the objects A and B, a wedging action will be established to prevent movement of the object B relative "to the'object A.

The end member 9 is composed of sections II` and I2 connected to each other by. a hingeI3 the pintle of which is indicated by the-character I4. The section I2 is connected to the side member I by a hinge I5'1`and a hinge I6 connects the section II tothe side member 6. The hinge i3 permits the sections II and I2 to swing relative to each other and'the hinges I5 and`l6 permit said sections to swing upon the side members 6 and l. When the sections II and I2 are moved toassume a position angularly to each other 'this brings about a movement 'of the side member I `toward the side' member 6,y the frame then becomes collapsed.

A member I1 is apertured to receive the pintle I4 of the hinge I3 and has formed thereon a ball I8 received within a socket-type coupling I9;

A feed stem 2Q is threaded in the end member 8 and one end thereof'is equipped'witha ball2l' received in the coupling I9. The coupling I9 vis of sectional formation to permit the balls of the stem and member 'I 'I to be assembled therein. A rivet 22 joins the sections of the coupling I9together. The'feed stem 29 mayrotate relative'to the member I1 andthe latter mayhave pivotalmovement with respect tol Athe feed stem due to the yarrangement of the coupling I9,`

The feedstem 20Lhas a handle 23 connected thereto nby a universal joint 24 which will permit positioning of the handle at different `angles to' the feed stem so that the latter may be rotated conveniently when the device is in use.

When it is desired to release the object B from the object A, the feed stem 20 is rotated by the handle 23 causing the sections II and I2 of the` end member 9 to move into angular position drawing the side member 'I toward the side member 6. Said side member 'I pivots in the notch 9 and the bail pivots on the end member 8 as well as on the member I or if desired, the bail may be moved off of the end member 8 prior to rotating the stem. Therefore, it will be seen that the frame 5 can be easily collapsed which will free the object B from the object A.

Referring to the use of the present invention to a marine way as shown in Fig. 5, a number of joggle wedges are employed between the slideways 25 and the groundways 26 to prevent the l Way.

slideways from moving or sliding on the groundways during the construction of a ship on the marine way. The ship under construction is designated by the character 2l and arranged between the bottom thereof and the slideways are packing blocks 28 and wedges 29 which are drivenl in between the packing blocks and the slideways for the purpose of levelling the ship on the marine It will be seen that the groundways are arrangedat opposite sides of the keel vof the ship and extend longitudinally of the latter and the top faces slope towards each other and the outer` edges are provided with upstanding flanges f 3l! extending substantially the full length of the groundways. The joggle wedges constructed in' accordance with the present` invention are arranged between the flanges '30 and the outer longitudinal edges of the slideways and establishv wedging action therebetween so that the slideways will not move over the groundways longitudinally of the latter. To prevent-the slideways from moving towards eachotherand after joggle wedges have been' arranged in position, said slideways are jacked away from each other and held in said position by spreaders (not shown). arranged between the slideways which place pressure on the joggle wedges.4 After the ship has been constructed and is readyfor launching, the joggle Vwedges must lbe removed and due to the present construction of the joggle wedges, it is a simple matter for-a person to easily and quickly collapse the joggle wedges by rotating the handles 23 thereof freeing the slideways from the groundways so that when the usual trigger mechanism of the marine way is operated., the slideways may then slide freely over the groundways to bring about launching of the ship, inthe Water.

`Therefore, it will beseen that the releasing of the joggle wedges can be carried out rapidly and with no danger of damage or'mutilation thereto so that the joggle wedges can be used as many times lVas, desired.

While I have shown and described the preferred embodiment of my invention, it is to be understood that minorA changes in construction, combination, and arrangement of parts may be made without departing from the spirit and scope of the invention as claimed.

Having thus described my' invention, what I claim is: i 1. In combination with a, marine way including groundways having opstanding flange portions, slid'able supporting slideways, joggle wedges arranged between the ange portions and the slideways and each. including Va collapsible wedge frame and manually operated means for collapsing the frame. i

2. A joggle wedge, a wedging frame including opposed portions, means hingedly connecting said portions, means opposed to said hinged means connecting said portions to sustain the frame in wedging position, and means for releasing one of said portions for movement toward the other portion for collapsing the frame.

3. In a joggle wedge, a wedging frame including side members, means connecting said members whereby one of the members may move toward the other member, a sectional 'end member hinged to the side members with the sections hinged to each other, and an operating means connected to the sections of said end member, whereby the sections may be moved into angular relation to each other for moving one of the side members toward the other side member.

4. In a joggle wedge, a, wedging frame including side members and end members, one of said end members formed integrally with one of the side members andy notched to receive the other side member, a bail pivoted to the latter-named side member and engageable withthe latter,- named end member, the other end member including hingedly connected sections, hinges connecting the sections to the side members, and an operating means connected to the sections for the movement thereof relative to each other and relative to the side members.

vv5. In a jogglefwedge, a wedging frame including side members and end members, one of said end members formed integrally with one of the side members and notched to receive the other side member, a bail pivoted to the latter-named side member and engageable with the latternamedv end member, the other end member including hingedly connected sections, hinges connecting the sections to the side members, a coupling connected to the sections of the sectional end member, and a feed stem threaded into the other end member and connected to said coupling.` j i 6. In a joggle wedge, a wedging frame including side members and end members, one of said end members formed integrally with one of the side members and notched to receive the other side member, a bail pivoted to the latter-named side membery and engageable with the latternamed end member, the other end member including hingedly connected sections, hinges'connecting the sections to the side members, a'coupling connected to the sections of the sectional end member, a feed stem threaded into the other end member and connected to said coupling,y a handle, and a universal joint connecting the handle to the feed stem.
